As some of you know, Im taking classes to be a Computer Technician. And I have a few tips for you to maintain your computer, some you most likely never heard of. Make sure your computer is in the right environment, ( Out of Direct Sunlight, not near anything that gives off Heat, etc) Check that air Vents on the computer case or monitor are not blocked by Books, drapes, paper, etc. This will cause the Computer to over heat, because of the lack of air. ( Most Important) Make sure the inside of the computer case is free from dust. Use an antistatic vacuum blower, or can of compressed air to blow the dust out of the case. Clean Vents, power supply and fans. You should always clean out the inside of your computer at least twice a year. If you don't, the dust will build up, and the computer, will slow down and overheat. This is what a Dust did to a PC. Compressed Air: An important note, If you are going to clean out your computer by yourself, make sure you have an Anti static wrist band. The Anti static wrist band prevents any static from damaging the computer. Even the Slighest amount of static, would damgage the motherbroad, making it useless. So before you go opening up your computer, make sure you have that anti static wrist band. Or, you can let a Technician to do it for you, or better yet, you can buy a dust cover for your computer, (however dust may still find a way inside.) 4. Protect your computer from power surges. When using devices like computers, TVs, etc, Use a Surge protector. This would help the ( in this case, computer) from being damaged, from a power surge, or "Spike", that can come from lighting strikes, or even brownouts. A Brownout is a " Sag" in the power. This is when the lights dim. But it's after the browout, where your computer can get damaged. After the brownout, ( A brownout last a few seconds) when the lights come back on full, there is a Surge. A Brownout happens more times then you think. Brownouts can occurr when the AC is being turned on, or even a Hair Drier thats being used. These things use a lot of power, and can " Drain" power. Causing the lights to dim. This is a part of what I know. Feedback would be great!
